Based on the part number **MHO+78FGD-R**, this component is a high-stability, voltage-controlled crystal oscillator (VCXO) or a fixed-frequency oscillator, typically manufactured by companies like **MtronPTI**. Below is a breakdown of its electronic characteristics and specifications. --- ### 1. Component Overview The MHO series generally refers to **Metal Hybrid Oscillators**. These are high-reliability components often used in telecommunications, networking, and industrial applications where timing precision is critical. ### 2. Technical Specifications Table | Feature | Description | | :--- | :--- | | **Package Type** | 14-pin DIP (Dual In-line Package), often metal-can for EMI shielding | | **Frequency Range** | Typically 1.000 MHz to 150.000 MHz (Varies by specific sub-model) | | **Supply Voltage** | Usually +5.0V DC (Standard for the MHO series) | | **Output Type** | HCMOS / TTL Compatible | | **Operating Temperature** | Commercial (0°C to +70°C) or Industrial (-40°C to +85°C) | | **Stability** | Usually ±25ppm to ±100ppm depending on the suffix | --- ### 3. Key Electronic Characteristics * **Hermetically Sealed:** The "Metal" part of the name indicates the component is housed in a metal container, vacuum-sealed or filled with inert gas to protect the quartz crystal from humidity and aging. * **Tri-State Functionality:** Many models in this series feature a "Tri-state" or "Output Enable" pin, allowing the output to be disconnected (high impedance) for testing or power saving. * **Low Jitter:** Designed for clock distribution where phase noise and timing jitter must be kept to a minimum to prevent data errors. * **RoHS Compliant:** The **-R** suffix typically denotes compliance with "Restriction of Hazardous Substances" (Lead-free). ### 4. Typical Applications 1. **Microprocessor Clocks:** Providing the base heartbeat for CPUs and MCUs. 2. **Network Hardware:** Used in switches and routers for synchronous data transmission. 3. **Test & Measurement:** Found in frequency counters and signal generators. 4. **Industrial Controllers:** Timing for PLCs and automation logic. --- ### 5. Pin Configuration (Typical 14-pin DIP) ```text Pin 1: NC (No Connection) or Tri-state Control Pin 7: Case Ground Pin 8: Output Signal Pin 14: +Vcc (Supply Voltage) ```
